        People on the other end of calls can't hear me. Can't see any microphone sensitiviy settings in setup. One person reported hearing a slight buzz.

          Just to clarify it has worked in the past, but I couldn't tell you when as I don't take many calls on this phone.

          It was definately working in 818, but not sure when it failed between there and around 833.

              Have you installed uVolMan from the OpenStore? If so look at the second setting down from the top of the screen.

                    Ok looks like it might be a pinephone issue rather than Ubuntu touch. Dropped back to RC Version 23 and forced a reinstall on all apps.

                    I've an application called recorder that is firing two error messages: "Failed to connect to stream: Access denied" and "Internal data stream error." both followed by "(Reset your settings will fix this.)". Resetting the settings in the application does not fix it.

                    Thoughtit may have been something todo with the privacy switch but this was in the on position, and changing it while the phone was powered up didn't seem to raise any notifications on the screen. The recorder app raised the same error with the mic switch in the off position. I've never used these switches before.

                      I have carried out a command line test of the microphone and it is just making static noise. Followed the instructions here:

                        Those instructions are for Ubuntu 20.04 not Ubuntu Touch. It is unlikely therefore to work on your phone.

                          @cliffcoggin Got any other suggestions? All functions executed without error, or needing to install anything. It recorded buzzing/static similar to whatis heardon calls.

                            Reverted to the RC and carried out a complete reset. Still no mic and same faults on the sound recorder.

                              I would try to burn another image on the SD of any other OS, for example Mobian. That way you're out of doubt.

                                  Did you consider a loosy electrical connection to the mic board ?
                                  Did you try to remove board and clean contacts ?

                                  Did you try to get help or infos from Pine 64 forums, for instance as this thread : http://forum.pine64.org/showthread.php?tid=15687 ?

                                    @cliffcoggin while the instructions mention 20.04, they are general enough to also work in 16.04. But probably not on Ubuntu Touch, because of confinement.

                                      Yup appears it was dodgy contacts to the microhone. Hadn't occurred to me that there were any spring contacts in the signal path, very close to the vibrator motor too.

                                      Wasn't anything obviously amiss but a strip pull up a few spring contacts and rebuild fixed it.

                                      As it happens the revorder app still doesn't work. Will try the command prompt test and respond here for completeness.

                                        Do not hesitate to clean once or twice a year every contact in the phone with alcohol or cleaning fluid F2.

                                        That kind of issue is current on pressure contacts, it's for instance one of the first cause of hardware failure in Fairphones.
